SSD (Solid State Disk)
This refers to a device that saves
information to semiconductors unlike a
normal hard disk drive (HDD). There are
two types of SSD. One saves data to
the DRAM and the other saves data to
the Flash Memory. Since there are no
mechanical parts, an SSD provides a
much better performance than an HDD.
Especially, a Flash Memory-Type SSD
provides high reliability and durability.
Network Administrator
A user who plans, congures and
manages network operations.
Sometimes, a network administrator is
called a system administrator.
Sleep Mode
A power mode that enables computers
to save power consumption when they
are not being used. When a computer
is in Sleep Mode, the data on the
computer memory is not saved to the
hard disk. If the power is tuned off, the
data in memory will be lost.
System File
System Files refer to les that are read
and used by the Windows operating
system. In general, system les must not
be deleted or moved.
USB (Universal Serial Bus)
This refers to a serial interface standard
developed to replace the conventional
interface standards such as Serial and
PS/2. While USB 1.1 supports 12Mbps
(12 million bits per second), USB 2.0
supports a data rate that is 40 times
(480Mpbs) faster than that of USB 1.1.
The data rate of USB 2.0 is equivalent to
that of IEEE1394. Therefore USB 2.0 is
used for A/V devices supported by IEEE
1394 and a 2nd HDD and CDRW that
require a high data rate.
Windows Media Player
A multimedia program included with
Windows. Using this program, you can
play a media le, create an audio CD,
listen to a radio broadcast, search and
manage media les, and copy les to a
portable device, etc.
